QR Codes– are they still a thing?

I’ll be at Bazaar Bizarre in a few weeks, and thought I’d make a sign that will help get people to my store.  So, dear internet, are QR codes still a thing?  I’m new to the smartphone game, and only recently downloaded a QR scanner.  The codes themselves (stands for Quick Recognition barcode, FYI) are very easy to create.  I made one that directs users to my store using http://createqrcode.appspot.com/

If you were able to scan that, it goes directly to my Etsy page.  I was thinking about printing it out, very large and pasting it onto a fruit-shaped sign. Thoughts?

Oh, technology!
